But when a call from a phone using port 5090 (UDP) is made to a phone which is using port 5060 (UDP), the call goes thru using "loose route" and the bell also rings but there is no audio.

Sorry, but that is not enough information to detect the issue. What I
suggest to you is:
- Do a capture of the SIP flow.
- Examine values in SDP (in INVITE and 200 OK) before and after
passing by the proxy.
- You should see that some SDP media address has not been modified by
rtpproxy so you could examinate why in your Kamailio script.
